Answer:
Noah is 17 and Tina is 7.
Why?
Let t represent Tina’s age.
So, 2t + 3 is Noah’s age.
This is your equation;
2t + 3 + t = 24
Now, simplify so t is on one side.
3t = 24 - 3
3t = 21
t = 21/3
t = 7
Tina’s age is 7, and Noah (according to the expression made for him) is 17.
Check:
7 + 17 = 24
Answer:
4x10=40-2=38
38% = 0.38 in decimal form. Percent means 'per 100'. So, 38% means 38 per 100 or simply 38/100. If you divide 38 by 100, you'll get 0.38 (a decimal number).

Step-by-step explanation:
14.50 (4) + 20= 78
12.50 (4) + 28= 78
Volume of a sphere=(4/3)πr³ ⇒r=∛(3v/4π)
volume of a sphere=950 in³
Therefore:
r=∛(3*950 in³/4π)=6.09834... in≈6.1 in
answer: radius=6.1 in
